Abstract

In order to study the effects of different water logging duration in growth stages ZGS11, ZGS13 and ZGS31 on root and shoot growth of three WHEAT genotypes Chamran, Vee/Nac and Yavaros, a pot experiment was carried out in the Ramin Agricultural and Natural Resources University in 2004. The experiment was a factorial according to a Randomized Complete Block Design with three replications. Study of ROOT DRY WEIGHT and root elongation trend showed different responses among genotypes, start of water logging periods and different water logging levels, as short period of water logging (10 days), had unrecoverable effects on the growth. Analysis of variance of ROOT DRY WEIGHT and ROOT LENGTH at the an thesis and physiological maturity stages indicated significant different among all of treatments levels. Vee/Nac genotype was found superior with respect of ROOT DRY WEIGHT and ROOT LENGTH to other genotypes. ZGS11 and ZGS31, had the highest and the lowest responses to water logging, respectively. Duration of 10, 20 and 30 days water logging at a thesis stage decreased 37.75, 44.31 and 54.01% of ROOT DRY WEIGHT, and 25.85, 47.02 and 58.88% of ROOT LENGTH compared to control, respectively. Investigation of the root anatomy of WHEAT genotypes under WATER LOGGING STRESS showed formation of cortical root PARENCHYMA as a water logging-resistance mechanism.
